On November 30, 2018, NMPA issued the Announcement on Issues Pertaining to the One-off Import of Reference Drugs for Biologicals in Clinical Trials (Announcement No. 94 of 2018), clarifying that the applicant can apply for one-off import of brand-name drugs that meet certain conditions as reference drugs for clinical trials. To further implement the relevant policies set forth in the Opinions on Deepening the Reform of the Review& Approval System to Encourage the Innovation of  Drugs and  Medical Devices (General Office [ 2017 ] No. 42), and further promote the reform of Streamlining Administration, Delegating More Powers to Lower-level Governments and Society, Improving Regulation and Optimizing Services, in light of the domestic enterprises' actual demand of biosimilar R&D, NMPA decided to grant the one-off import of brand- name drugs as reference drugs for biosimilar clinical research that are produced by the same manufacturer in different places of origin, and have been approved for import registration or clinical trial in China. The Announcement was issued on May 28, 2019. The relevant issues are hereby announced as follows:
